Safety first for relay
25 August 2009
Relay interface module for plant, process and machinery guarding, and emergency stop applications.
Raising standards for safety critical circuits, Finder has introduced a compact 2 pole, 8 A relay interface module. Conforming to the EN50205 type B standard, the 48.12 features forcibly guided changeover contacts (1 NO and 1 NC) to enable positive monitoring of switching contact states and large physical separation between adjacent contacts to remove any risk of flashover. To help minimise panel space and to ensure rapid installation, the Finder 48.12 safety relay interface module measures just 15.8 mm wide, provides screw terminal connection and is designed for standard 35 mm rail mounting.
Where required, an 8-way jumper link is also provided for commoned connections. The 48.12 features a 0.5 W DC sensitive coil, available as standard in 12 V and 24 V versions. The wide compatibility that results means far greater flexibility for circuit designers in a wide range of plant, process and machinery guarding, emergency stop and critical monitoring applications.
